Apparently this a thing. A youtube search of “sewer fishing” yields a surprising amount of matches. Hence, there are a lot of fish the our sewers (and apparently, people willing to interact with them). We’re not sure what’s more awesome, the fact that animals can thrive despite our disgusting waste pipes funneling refuse into their pristine ecosystems, or that people are savvy enough to catch them.
Either way, we’re trying this once the weather gets better.
